Description

[Detailed description of the invention] The present invention relates to a rafter decoration, and more specifically, the cross section from the outdoor peripheral end of the frame part 2, which is formed in a substantially cylindrical shape to be wrapped around the outer circumference of the end of the rafter 1, toward the inner peripheral direction. An L-shaped frame part 4 is extended to form a substantially U-shaped cross section at the outdoor end of the frame part 2, and is engaged perpendicularly to the longitudinal direction of the rafter 1 from the tip of the frame part 4 toward the outer circumference. A locking groove 6 is formed between the frame portion 4 and the locking piece 5 by extending the locking piece 5.
The flange 8 is formed into a substantially cylindrical shape and extends from the periphery of the mirror plate 70 for covering the end 3 of the rafter 1 into the locking groove 6.
An elastic engagement piece 9 extending from the tip end so as to be folded back toward the inner circumferential direction is engaged with the outdoor surface of the engagement piece 5 to prevent the flange 8 from coming off from the engagement groove 6. This relates to rafter decorations.

In conventional rafter decorations, as shown in FIGS. 1 to 3, the flange 8 of the end plate 7 did not have the elastic retaining piece 9, so the flange was not provided in the locking groove 6 of the frame 2. Even if the flange 8 is inserted, the flange 8 does not get caught and easily comes off from the locking groove 6. Therefore, when attaching the rafter decoration to the rafter, the mirror plate is easy to come off from the frame before fixing the rafter decoration to the rafter, so installation is difficult. It was difficult to do.

In particular, as shown in Figures 1 and 2, the frame is divided into multiple parts, and these divided frames can be slid vertically or horizontally to expand and contract to fit the rafters. Due to the large number of parts used to decorate the rafters, the mirror panels and frames were more likely to come off during construction.

The present invention was made in view of the above-mentioned conventional drawbacks, and its purpose is to extend the elastic engagement piece to the flange and lock it to the locking piece of the frame, so that the end plate is To provide a rafter decoration that does not come off from a frame part and can be easily installed on the rafters during construction.

The present invention will be explained in detail below with reference to the accompanying drawings.

A substantially cylindrical frame portion 2 is wound around the outer periphery of the end of the rafter 1, and a frame portion 4 extends from the peripheral end located on the outdoor side than the end 3 of the rafter 10 toward the inner circumference, The frame part 4 is formed into a cross-sectional shape by bending the tip of the frame part 4 toward the indoor side, and is locked perpendicularly to the longitudinal direction of the rafter 1 from the inner circumference of the frame part 4 toward the outer circumference. A locking groove 6 is formed between the frame portion 4 and the locking piece 5 by extending the piece 5 .

Also, this frame portion 2 is an L-shaped 4-piece together with the frame portion 4 and the locking piece 5
pieces 2 a y 2 b; t 2 c t2d
The frame part 2 is this piece 2a.

2 b, 2 c t 2 d are formed by overlapping their ends, and these pieces 2 a) 2
b 12 c t2d By sliding the comrades vertically or horizontally to change the overlapping margin, the frame portion 2
can be expanded and contracted to fit the rafter 10 dimensions exactly.

From the periphery of the plate-shaped mirror plate 70 in contact with the end 3 of the rafter 1, a flange 8 extends in a substantially cylindrical shape toward the locking groove 6 of the frame 2, and extends from the tip of the flange 8 in the inner circumferential direction. Spring elastic engagement piece 9
The elastic engagement piece 9 is extended and inclined slightly toward the indoor side, and the tip of the elastic engagement piece 9 is locked to the outdoor side surface of the locking piece 5.

It is not necessary to lock the elastic engagement piece 9 to the locking piece 5 by bringing the tip of the elastic engagement piece 9 into perfect contact with the locking piece 5, and the elastic engagement piece 9 does not need to be in contact with the locking piece 5 in the locking groove. It is sufficient that the elastic engagement piece 9 comes into contact with the locking piece 5 and locks it when the collar part 8 tries to come out of the locking groove 6 when it is loosely fitted into the locking groove 6.

The elastic engagement pieces 9 may be provided along the entire circumference of the flange 8, or may be provided at multiple locations on the flange 8.

Therefore, during construction, the elastic engagement piece 9 is inserted into the locking groove 6 together with the flange 8 while being elastically bent toward the indoor side, as shown in FIG. 6, as shown in Figure 6, the elastic engagement piece 9 opens as before due to its spring properties and locks onto the outdoor surface of the locking piece 5, and then opens again. This prevents the collar portion 8 from coming off from the locking groove 6.

Incidentally, the rafter decoration is formed of a copper plate or the like, and its shape is not limited to the square shape as shown in the figure, but may be round shape, and the mirror plate may also be divided into sections so that it can be expanded and contracted.

As described above, the present invention extends the flange from the periphery of the end plate into the locking groove of the frame, and connects the elastic engagement piece extending from the flange toward the inner circumference to the outdoor side of the locking piece. Since it is locked on the surface of the rafter, once the flange of the head plate is inserted into the locking groove when attaching the rafter decoration to the rafter, the elastic engagement piece will lock on the locking piece and the head plate will not come off from the frame. It has the advantage of being easy to construct.

In particular, when the frame is divided into multiple pieces and can be expanded and contracted, the frame and the sharp part can be separated by locking the locking pieces of each piece of the frame and the elastic engagement pieces of the end plate, respectively. At the same time, each piece of the frame is brought together through the end plate and does not come apart, making construction extremely easy.
